Abstract: RAILWAY CAR BRAKE RIGGING   FULCRUM LEVER MOUNTING          Abstract of the Disclosure The upper end of a railway car live brake lever between the axles of a car truck is pivotally connected to one end of a link that extends across the top of the adjacent axle and is pivotally connected to the lower end of a vertical ful-crum lever.  The central portion of the fulcrum lever is pro-vided with a circular opening, the wall of which is convex from side to side of the lever and forms an arc of a circle. A rigid supporting member for the fulcrum lever projects later-ally from one side of the center sill of the car and has a hook at its outer end extending through the lever opening and curved away from the live lever.  The hook forms an arc of a circle and has a circular cross section, the radius of the in-side of the hook being substantially the same as the radius of said wall arc.  The inside diameter of the lever opening is only slightly greater than the diameter of the hook in cross section, and the upper end of the fulcrum lever is formed for connection to a device for rocking that lever around the hook.

Abstract: ABSTRACT OF THE DISCLOSURE A method and treating agent for increasing the yield of oxidized coal or coal from surface or strip mines where said coal particles are concentrated by froth flotation.  The method consists of utilizing as a flotation promoter or frothing aid an invertible water in oil emulsion of sodium polyacrylate in a dosage calculated as 0.017 - 0.5 lb. of dry sodium polyacrylate per ton of dry coal.  The preferred treating agent for oxidized coal undergoing froth flotation is an invertible water-in-oil emulsion of sodium polyacrylate.  The latex emulsion has demonstrated superiority as a flotation promoter for oxidized coal over the dry polymer and exhibits synergism over the dry polymer and over the components of the latex emulsion including a paraffin solvent, a hydrophobic emulsifier such as sorbitan monooleate, a solvent such as Espesol 3-E* (Charter; an aromatic blend) and stabilizers such as polyisobutylene and aluminum tristearate.

Abstract: ABSTRACT OF THE DISCLOSURE    A data acquisition and display device for acquiring and displaying the time history of the variations in an analog value includes digital circuitry which employs a staircase voltage generator operated at a first frequency to quantize a range of analog voltages which correspond to the  expected variations in the analog value.  When the staircase voltage equals an analog voltage corresponding to the instantaneous value of the analog value, a memory device is conditioned to receive data corresponding to the staircase value.  The memory acquires the data at a second frequency selected by the operator to acquire a fixed number of data inputs over a selected time period for which the time history is desired, and the circuitry automatically terminates data acquisition when the fixed number of data inputs is acquired.  The data is read out at a third fre-quency selected by the operator.

Abstract: ABSTRACT OF THE DISCLOSURE                A briquetting plant for hot briquetting particulate matter, such as mill waste containing a material that softens when heated, such as iron oxide, which includes a low tempera-ture tumble type heat exchanger, an intermediate temperature tumbler type heat exchanger, a fluid bed furnace and a compactor, with the feed material being fed therethrough in succession. The briquettes produced by the compactor are first fed from the outlet of the compactor into the intermediate temperature heat exchanger, for liberation of heat therein, separated from the feed material by a screen at the outlet of the intermediate temperature heat exchanger and from such screen transported into the low temperature heat exchanger for further imparting of heat to the feed material.  A second screen is provided at the outlet of the low temperature heat exchanger for separating an discharging the briquettes in relatively cooled form.  The tumbler type heat exchangers are in the form of a hollow cone having a wide included angle enclosed by a cover and slowly rotated about an included axis to provide intimate mixing of the components and uniform withdrawal of the mixture.  The heat exchangers are mounted at a low level and the screens are mounted at a high level with bucket type elevators in between and with the furnace and compactor being located at successive intermediate levels so that, except for the two bucket elevators, all of the flow in the plant takes place under action of gravity.  Wet and dry feed materials are separately handled, with means being provided for conveying the dry feed directly to the second heat exchanger.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention is concerned with a metal casting having a hardened surface layer formed of a casting metal and alloying elements, wherein the hardened surface layer contains grains of a refractory material uniformly distributed through-out its thickness forming inclusions of the refractory material in the hardened surface layer, the alloying elements being such as to impart to the casting metal alloy adequate toughness to retain the inclusions therein;  the casting metal and alloying elements extend between the spaces defined between the grains forming the inclusions of the refractory material, and thus retain the inclusions in the surface layer.  The metal casting of the invention is manufactured by preparing a foundry paste by mixing together powder alloying elements with a binder and admixing thereto a powder refractory material in combination with a flux; applying a layer of the foundry paste upon the surface of a foundry mould; drying the layer; contacting the layer with a liquor of the same flux; drying the thus formed layer, and filling the foundry mould with overheated molten casting metal such that the molten metal penetrates into the foundry paste layer to retain the grains of refractory material forming the inclusions in the formed hardened surface layer. The refractory inclusions in the metal castings of the inven-tion which are found in the hardened surface layer make it possible to increase the resistance of the castings to the destructive effects produced by hydrodynamically acting molten metal jet and thus to prolong the service life of the castings.
